helical

Examples of helical in the following topics:

• Helical Motion

  • Helical motion results when the velocity vector is not perpendicular to the magnetic field vector.
  • This produces helical motion (i.e., spiral motion) rather than a circular motion.
  • Describe conditions that lead to the helical motion of a charged particle in the magnetic field

• Direction of the Magnetic Force: The Right Hand Rule

  • Because the force is always perpendicular to the velocity vector, a pure magnetic field will not accelerate a charged particle in a single direction, however will produce circular or helical motion (a concept explored in more detail in future sections).

• LCDs

  • The molecules arrange themselves in a helical structure (twisted structure).

• Springs

  • Plot of applied force F vs. elongation X for a helical spring according to Hooke's law (solid line) and what the actual plot might look like (dashed line).

• Electric vs. Magnetic Forces

  • The angle dependence of the magnetic field also causes charged particles to move perpendicular to the magnetic field lines in a circular or helical fashion, while a particle in an electric field will move in a straight line along an electric field line.
